我正在使用Oxford api来获取Python中单词的含义。这是我的代码：
import requests
import json
app_id = 'My-App-ID'
app_key = 'My-App-Key'
language = 'en'
word_id = 'help'
url = 'https://od-api.oxforddictionaries.com:443/api/v1/entries/'+ language + '/'+ word_id.lower()
#url Normalized frequency
urlFR = 'https://od-api.oxforddictionaries.com:443/api/v1/stats/frequency/word/' + language + '/?corpus=nmc&lemma=' + word_id.lower()
r = requests.get(url, headers = {'app_id' : app_id, 'app_key' : app_key})
#print("code {}\n".format(r.status_code))
print("text \n" + r.text)
#print("json \n" + json.dumps(r.json()))
我得到的输出如下

这里的单词id“help”，其信息显示在输出中。我想只提取定义部分。见下文：
"definitions": [
"make it easier or possible for (someone) to do something by offering them one's services or resources"
],
您可以看到输出中有一个定义部分。如何在Python中执行此操作？可用的定义很多，我只想要第一个定义。
y = json.loads(r.text) #filename should be the file where your json is saved
y = y["results"][0]["lexicalEntries"][0]["entries"][0]["senses"][0]["definitions"]
for definition in y:
print (definition)
print("\n")
